JOHN P. SMITH, OF CHICAGO, ILLINOIS, ASSIGNOR TO INTERNATIONAL HARVESTER COMPANY OF NEW JERSEY, A pORPORATION OF NEW JERSEY.

Application filed January 29, 1914.

To all whom it may concern:

Be it known that I, JOHN P. SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Shocking-Machines for Grain and the like, of which the following is a full, clear, and exact specification.

My invention relates to shocking machines for grain and the like.

In shocking machines of the type wherein the shock is built prostrate in a shocker cradle it has heretofore been proposed to provide resilient means carried on standards on the shocker frame at the sides of the cradle, which, while permitting the sheaves to be freely delivered to and discharged from the cradle, prevent any such w shifting movement of the sheaves in the latter as would interfere with the binding or setting of the shock.

My invention has for its object to improve and simplify such holding means for the sheaves in such a manner that efficiency and life of the same are materially prolonged. I attain this object by the provision of improved holding members resiliently mounted on the frame standards in an improved manner as hereinafter described.

In the accompanying drawings I have illustrated one embodiment which my invention may assume in practice.

' Figure 1 is a rear elevation of a shocker equipped with my improvement;

Fig. 2 is a side elevation of the same;

Fig. 3 is a sectional view taken on line 33 of Fig. 2, looking in the direction of the arrow, showing the detail of the holding mechanism.

The shocker shown is of the standard Raney construction, comprising a frame 1, transport wheels 2, a sheaf receptacle or cradle 3 pivoted at 4 upon the rear of the frame and normally reclining thereon, and cradle dumping mechanism 5 operatively connected, through suitable mechanism 6,to the knotter shaft 7 of the shocker. As in the usual Raney construction, the frame 1 is also provided with a plurality of upstanding arms or standards 8 and 9, disposed at the rear thereof and on opposite sides of the cradle 3, the standard 8 preferably being formed of angle material, while the standard 9 is formed of a fiat bowed strip. Both of these standards project up a sub- Specification of Letters Patent.

stantial distance above the top of the cradle. Carried upon these standards, at a point near their upper ends and projecting inwardly toward each other and over the cradle bottom, are my improved sheaf positioning members.

As shown, a substantial U-shaped bracket 10 (Fig. 1), having a plurality of oppositely disposed lugs 11, is attached to the side of each of the standards 8 and 9 by means of bolts 12 passing through these lugs. Pivoted upon a horizonally disposed hook or lug 13, projecting inwardly and forwardly from the rear end of each bracket (Fig. 3), is a sheaf holding member shown in the form of a rigid tine 14, preferably slightly downwardly curved toward its inner end. This tine 14 is provided with an eye-shaped outer end which fits around the hook 18 in such a manner as to attach the tine thereto and at the same time permit the tine to be swung downwardly or rearwardly about the hook 13 as an axis, toward or from the dotted line positions shown in Figs. 1 and In this connection it is to be noted that the normal position of the tine; 2'. 6., wherein the same strikes against the edge of the standard, is shown in full lines in Fig. 3, and that the extreme rearward position of the same is shown in the lower dotted line position therein indicated, wherein the tine strikes against the abutment formed by the end wall of the U-shaped bracket mem- It is further to be noted that the tine is guided in its movement in a horizontal plane by an arcuate, horizontally disposed rearwardly extending guiding portion 15 formed integral with the bracket against the lower surface of which the tine 14: is normally held in contact by a helical spring 16, having its lower end attached to the tine at a point adjacent its pivot and extending upward and. slightly forward to a point 17, where its upper end is attached to the standard.

As the sheaves are delivered to the sheaf receiving cradle 3, either normally or, for instance, in the manner that the same are delivered in shockers of the well known Raney type, the tines 14: will obviously yield when struck by a sheaf, turning clownwardly about their pivots on the hooks 13, as shown in Fig. 1, in such a manner as to permit the sheaves to be placed in the cradle. Obviously, when the sheaves have passed the tines the spring 16 will again pull the same upward to their up, or normal positions indicated in full lines in Figs. 1 and 3. During the dumping of the shock; i. 6., as the cradle 3 moves backward about its pivot on the frame and the prostrate sheaves therein are turned to vertical position, it is likewise obvious that when the sheaves strike the tines 14:, the latter will yield freely rearwardly toward the dotted line positions shown in Fig. 3 in such a manner as not to interfere with the dumping op eration, the springs 16 in this instance also acting to return the tines to their normal position, due to the fact that the turning action of the tines as they move outward stores in the springs not only the energy requisite to pull the tines 14: toward the surface of the arcuate portion 15, but also to swing the same around on their pivots to the full line position shown.

It is to be noted that in this construction, by the provision of the rigid tines and the pivoting of the same upon the standards all tendency for the holding means to bend or break in service is effectually prevented, the tines swinging freely downward or back ward about substantial pivots on the brackets. It is also to be noted that, due to the improved spring returning mechanism therefor and the improved manner of connecting the same to the tines, the strain upon these springs is also minimized at the same time that a rugged and simple construction is provided.

While I have in this application described one form which my invention may assume in practice,'it is, of course, to be understood that the embodiment shown herein is used for purposes of illustration and may be modified without departing from the spirit of my invention.
